/**
* @file cairo-dock-module-instance-manager.h This class defines the instances of modules.
*
* A module-instance represents one instance of a module; it holds a set of data: the icon and its container, the config structure and its conf file, the data structure and a slot to plug datas into containers and icons.
* All these parameters are optionnal; a module-instance that has an icon is also called an applet.
